"This invention pertains to gas holders and relates more particularly to. that type. known as waterless holders, such holders being set forth andclaimed in LettersPatent to J agschitz, No. 1,275,696 dated August 13, 1918. In the structure disclosed in that patent a piston-like closure is employed in conjuncface of the. shell, means being provided to tion with the shell of the holder and a gas tight joint is effected between said member and the shell by theutillzation of shoes and a liquid sealing medium heldin working relation with said shoes to'afliord a sealing effect as well as a lubricating effectbetween.

the shoes and the holder.

The present invention relates to a structure of the same general type except that a different-sealing arrangement is employed and the presence or necessityof the shoes is done away with. Broadly stated, the structure may be said to comprise a shell, a pistonlike closure and a felt sealingring interposed between thepiston-likeclosure and the inner properly lubricate the sealing device.

The'invention is illustratedin the annexed Figure 1 is a Vertical sectional View of a portion of a waterless gas holder, the closure and the sealing means employed be tween the two, taken on the line II of Figure 2 a vertical sectional View taken onthe line IIII of Figures 1 and 3; and

Figure 3 a top plan View partly-in section. i

i The gas holder proper is polygonal in outline'and is composed of a series of plates 1 connected at their adjacent edges to corner posts of suitable form and shown in the instant case as formed'of an inner member 2 and a stiffening supporting member 3 whlch Q may take any desired structurallform. The

Extending outwardly from the lower portion, of the piston-like closuree is a shelf t '5, the shelf extending entirely around the circumference of the closure adjacent the a tight seal about the edges of loweredge thereof and ter ninajtii'ig short of the inner face of the Wall of the shell, Mounted upon and supported by the shelf is a plurality of layers of fibrous absorbent material, preferably felt, indicated 6.

Layers :of cloth may. likewise be em loyed:

Overlyingthe feltis a flexible plate 7, said plate extending inwardly and being secured by. a liquid tight joint to the: verticalwall of thelclosure. i

i The shelf andtlie plate 7 form, in effect,

a pocket forfthe reception of a lubricatin and sealing medium (coaltar, viscous or,

or the like). introduced into the same through pipes 8 which arecbimected; zit theirloweif ends, intoopenings in the plate 'Z, the upper end of the pipes opening into reservoir 9 securedto andcarriedjby the iswnie.

The plates 14 are substantially co-extensive of the felt and the blocks 15 are located at intervals around the piston in suflicient number to insure the felt being moved outwardly at all times and held in such outward position in order to effect a gas tight seal between the outer edge of the felt and the inner face of the wall of the holder.

Where the felt contacts the corner posts it will be notched out, as best shown in Figure 3, so as to conform with said member and effect a tight joint not only with the face of said member 2 but likewise with the edges thereof.

The various felt layers may be stitched or otherwise temporarily secured together in order to prevent disarrangement of the layers both in initial positioning of the same and during subsequent operation of the seal.

Any suitable liquid may be employed to lubricate the felt and to afford a liquid film between the felt and the wall of the holder. The static head of the liquid will be sufficient to keep the felt impregnated at all times and no wastage of the liquid will take place as there will be no flow through the felt while the piston head is at rest but only a slight flow when the piston head is moving and the felt is placed under more or less drag at its outer edge due to such movement.

Having thus described the invention, what is claimed is: V

1. In a waterless gas holder, the combination of a shell; a piston-like closure therefor; a shelf secured to the circumference of the closure and extending around the same, the outer edge of said shelf stopping short of the wall of the shell; a body of felt mounted upon the shelf; a plate overlying the felt extending inwardly and connected to the closure thereby forming a pocket; means for constantly urging the felt outwardly into contact with the wall of the shell; and a reservoir for liquid communicating with the pocket aforesaid.

2. In a waterless gas holder, the combination of a shell; a piston-like closure therefor; a shelf secured to the lower portion of the closure and extending circumferentially around the same, the outer edge of the shelf stopping short of the wall of the shell; a body of felt resting upon the outer portion of the shelf and contacting the wall of the shell; a flexible plate overlying the felt, extending inwardly therefrom and connected to the body of the closure, said plate and the shelf aforesaid forming in effect a pocket in rear of the felt; means for holding the outer edge of the plate against undue upward movement; means for urging the felt outwardly between the shelf and the plate; and

a reservoir for a sealing and lubricating liquid located above and connected to the pocket.

3. In a waterless gas holder, the combina tion of a shell; a piston-like closure therefor; a shelf secured to the lower portion of the closure and extending circumferentially about the same, the outer edge of the shelf stopping short of the wall of the shell; a body of felt resting upon said shelf adjacent the outer edge thereof and contacting the adjacent wall of the holder; a hold-down plate overlying the felt; means for holding said plate in proper position; a plurality of perforate plates placed against the inner face of the felt; means for pressing said plates outwardly, and a reservoir for liquid located above the felt and communicating with the pocket or chamber formed in rear thereof by the shelf and the overlying plate.

In testimony whereof I have signed my name to this specification.
